Compared with prior art, the Advantageous Effects of the technical scheme that the embodiment of the present application is proposed includes:
The embodiment of the present application discloses a kind of speaker, in the case of being provided with double diaphragm, further by separating bone
Inside loudspeakers is divided into multiple cavity by frame, and makes multiple cavity be connected with speaker space outerpace by going out acoustic aperture respectively
Logical, thus, make each vibrating diaphragm can be transmitted to outside speaker at sound wave produced by different directions, do not increase speaker thickness
In the case of, improve the output sound pressure level that speaker is radiated.
Below in conjunction with the accompanying drawing in the application, the technical scheme in the application is carried out clear, complete description, aobvious
So, described embodiment is a part of embodiment of the application rather than whole embodiments.Based on the enforcement in the application
Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, all belong to
Scope in the application protection.
As it was previously stated, according to the set-up mode difference of aforesaid separation skeleton, the embodiment of the present application is respectively by Fig. 2 and Tu
3 provide corresponding structural representation.
As in figure 2 it is shown, the middle part separating skeleton 23 is connected with the second vibrating diaphragm 24, separate the lower edge of skeleton 23 less than magnetic conduction
The upper edge of body 28, thus, inside loudspeakers is divided into tri-cavitys of A, B, C as depicted, wherein, cavity A and cavity C phase
Connection.When voice coil loudspeaker voice coil 26 occurs to move up and down, the first vibrating diaphragm 22 is driven to shake by speech coil framework 25, thus generation sound
Ripple, the vibrations of the first vibrating diaphragm 22 pass to the second vibrating diaphragm 24 by separating skeleton 23, and the second vibrating diaphragm 24 produces sound wave by vibrations.
Two surfaces of the first vibrating diaphragm 22 and the second vibrating diaphragm 24 all can radiative acoustic wave, wherein, the first vibrating diaphragm 22 forward directed radiation
The direct onwards transmission of sound wave of (diagram upper surface is produced), the sound wave of radiation backward (diagram lower surface is produced) enters cavity
A, then through cavity C, it is delivered to speaker rear by the acoustic aperture 29 that goes out set by the bottom of frame 21, the second vibrating diaphragm 24 is forward
The sound wave of radiation (diagram upper surface is produced) enters cavity B, then is transmitted by the acoustic aperture 29 that goes out set by top of frame 21
To speaker front, and the sound wave that the second vibrating diaphragm 24 radiates (diagram lower surface is produced) backward enters cavity C, by frame 21
The acoustic aperture 29 that goes out set by bottom be delivered to speaker rear.
By above-mentioned sound wave transmittance process, the sound wave of the first vibrating diaphragm 22 forward directed radiation with go out acoustic aperture 29 from top and spread out of
The sound wave of the second vibrating diaphragm 24 forward directed radiation superimposed, improve the output sound pressure level in speaker front, on the other hand, first shakes
The sound wave that film 22 radiates backward is superimposed with the sound wave that the second vibrating diaphragm 24 radiates backward in cavity C, go out from bottom acoustic aperture 29 to
Speaker rear exports, and improves the output sound pressure level at speaker rear, in actual application scenarios, if speaker rear
Be provided with baffle plate or there is the barriers such as wall, then the sound wave that speaker rearward radiates, after reflection, meeting is further
Superimposed with the sound wave forwards radiated, heighten the output sound pressure level of speaker further, thus, do not increasing speaker thickness
In the case of the output sound pressure level of speaker is greatly improved.
As it is shown on figure 3, the lower edge separating skeleton 33 is connected with the second vibrating diaphragm 34, separate the lower edge of skeleton 33 higher than magnetic conduction
The upper edge of body 38, thus, inside loudspeakers is divided into two cavitys of A, B as depicted.Move up and down at voice coil loudspeaker voice coil 36
Time, driving the first vibrating diaphragm 32 to shake by speech coil framework 35, thus generate sound wave, the vibrations of the first vibrating diaphragm 32 are by separating
Skeleton 33 passes to the second vibrating diaphragm 34, and the second vibrating diaphragm 34 produces sound wave by vibrations.
Two surfaces of the first vibrating diaphragm 32 and the second vibrating diaphragm 34 all can radiative acoustic wave, wherein, the first vibrating diaphragm 32 forward directed radiation
The direct onwards transmission of sound wave of (diagram upper surface is produced), the sound wave of radiation backward (diagram lower surface is produced) enters cavity
A, then it is delivered to speaker rear, the second vibrating diaphragm 34 forward directed radiation (diagram by the acoustic aperture 39 that goes out set by the bottom of frame 31
Upper surface is produced) sound wave enter cavity B, then by going out before acoustic aperture 39 is delivered to speaker set by the top of frame 31
Side, and the sound wave that the second vibrating diaphragm 34 radiates (diagram lower surface is produced) backward enters cavity A, set by the bottom of frame 21
The acoustic aperture 39 that goes out put is delivered to speaker rear.
By above-mentioned sound wave transmittance process, the sound wave of the first vibrating diaphragm 32 forward directed radiation with go out acoustic aperture 39 from top and spread out of
The sound wave of the second vibrating diaphragm 34 forward directed radiation superimposed, improve the output sound pressure level in speaker front, on the other hand, first shakes
The sound wave that film 32 radiates backward is superimposed with the sound wave that the second vibrating diaphragm 34 radiates backward in cavity A, go out from bottom acoustic aperture 39 to
Speaker rear exports, and improves the output sound pressure level at speaker rear, in actual application scenarios, if speaker rear
Be provided with baffle plate or there is the barriers such as wall, then the sound wave that speaker rearward radiates, after reflection, meeting is further
Superimposed with the sound wave forwards radiated, heighten the output sound pressure level of speaker further, thus, do not increasing speaker thickness
In the case of the output sound pressure level of speaker is greatly improved.
